Description

This disclosure relates to an anti-vibration member and an attachment.

Conventionally, there is known a sliding window that has two shoji screens that can be moved left and right inside the frame, and that has anti-sway members attached to the upper and lower ends of the mating frames of each screen, each of which has a guide groove that clamps the rails of the frame from the inside and outside directions (see, for example, Patent Document 1, etc.).

JP 2014-152442 A

Normally, there is a gap between the guide groove of the anti-vibration member and the rail, so the anti-vibration member is provided with a plate-shaped fin member made of soft resin to block this gap. The fin member has multiple notches in it to allow for easier work when fitting the shoji screen onto the rail. As a result, these notches can impair airtightness, and there is a risk that outside air will flow into the room.

Therefore, the inventors have come up with a problem of how to easily reduce the inflow of outside air through the slits in the fin members.

The anti-sway member disclosed herein is a anti-sway member that is attached to a shoji screen that is placed inside the frame that constitutes a window and is movable in the left-right direction along a rail, and includes an anti-sway member body having a guide groove that accommodates the rail so as to sandwich it from the indoor/outdoor direction, a fin member that has multiple cuts and is installed to close the gap between the rail and the guide groove, and at least one shielding member that shields the multiple cuts of the fin member.

Embodiments of the present disclosure will be described in detail below with reference to the drawings. FIG. 1 shows a sliding window 1 as seen from the outside of the room. The sliding window 1 is constructed by fitting two shoji screens, an outer shoji screen 3A located on the outside of the room and an inner shoji screen 3B located on the inside of the room, inside a rectangular frame body 2 formed of an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24, so that they can move left and right.

The outer screen 3A is constructed by fitting glass 35 inside a rectangular frame body 30A made up of an upper frame 31A, a lower frame 32A, a vertical frame 33A arranged on the door end side, and an outer meeting frame 34A arranged on the door tail side. The inner screen 3B is constructed by fitting glass 35 inside a rectangular frame body 30B made up of an upper frame 31B, a lower frame 32B, a vertical frame 33B arranged on the door end side, and an inner meeting frame 34B arranged on the door tail side. Both the outer screen 3A and the inner screen 3B have a vertical construction with upper frames 31A, 31B and lower frames 32A, 32B attached between the vertical frame 33A and the outer meeting frame 34A, and between the vertical frame 33B and the inner meeting frame 34B.

The upper and lower ends of the outer and inner screens 3A and 3B engage with the exterior and interior rails provided on the upper and lower frames 21 and 22 of the frame body 2, respectively. This allows the outer and inner screens 3A and 3B to be guided by these rails and moved left and right. Figure 3 shows the exterior and interior rails 211 and 212 provided on the upper frame 21. The exterior and interior rails of the lower frame 22 are provided to face the exterior and interior rails 211 and 212 of the upper frame 21. X1 in the figure indicates the exterior side, and X2 indicates the interior side.

As shown in Figures 2 and 3, the upper end 34A1 of the outer frame 34A of the outer screen 3A is provided with a vibration-stop member 4 that accommodates the exterior rail 211. The vibration-stop member 4 is fixed to the upper end 34A1 of the outer frame 34A with a mounting screw (not shown).

The specific structure of the anti-vibration member 4 will be described with reference to Figures 4 to 8. The anti-vibration member 4 is composed of an anti-vibration member body 41 having a guide groove 412 that accommodates the outdoor rail 211 so as to sandwich it from the indoor/outdoor direction, a fin member 44 that is accommodated inside the anti-vibration member body 41 and is an airtight member that seals the gap between the outdoor rail 211 and the guide groove 412, and a fin-shaped shielding member 45 that is overlapped on the fin member 44 and is a shielding member that supplementarily enhances the airtightness of the fin member 44.

The anti-sway member body 41 is made of a resin block. As shown in Figs. 4 and 5, a front plate portion 411 is provided on the front end side of the anti-sway member body 41. As shown in Figs. 2 and 3, the front plate portion 411 is positioned so as to be exposed on the outer visible surface 34A2 of the outer joint frame 34A when the anti-sway member 4 is attached to the upper end portion 34A1 of the outer joint frame 34A.

A screw insertion hole 411a is opened at the bottom of the front plate portion 411. The screw insertion hole 411a is a hole through which a mounting screw (not shown) is inserted to screw the anti-sway member main body 41 to the upper end portion 34A1 of the outer assembly frame 34A. As shown in Figures 2 and 3, the screw insertion hole 411a is covered by a cap 413 after the anti-sway member 4 is attached to the outer assembly frame 34A.

The guide groove 412 is recessed from the upper end surface 41a of the anti-sway member body 41 and penetrates the anti-sway member body 41 along the extension direction of the outdoor rail 211. As shown in Figures 4 and 5, the groove width of the guide groove 412 along the indoor/outdoor direction is narrowest at the opening 412a located on the upper end surface 41a of the anti-sway member body 41. The guide groove 412 gradually widens from the opening 412a along the depth direction, and then is formed with a constant width toward the groove bottom 412b.

As shown in Figures 4 to 7, the anti-vibration member body 41 has a fin member accommodating groove 414 in the form of a vertically long slit. The fin member accommodating groove 414 penetrates the anti-vibration member body 41 in the indoor/outdoor direction so as to be approximately perpendicular to the guide groove 412. The fin member accommodating groove 414 does not open to the upper end surface 41a of the anti-vibration member body 41.

The fin member 44 and the fin-shaped shielding member 45 are each made of soft materials such as resin and rubber in the shape of a rectangular thin plate, and thus both have flexibility. As shown in FIG. 5, the fin member 44 and the fin-shaped shielding member 45 are inserted into the fin member housing groove 414 from the side of the anti-vibration member main body 41 while overlapping each other. As a result, the fin member 44 and the fin-shaped shielding member 45 are removably housed inside the anti-vibration member main body 41.

The fin member 44 has one vertical slit 441 and three horizontal slits 442a, 442b, and 442c that are approximately perpendicular to the vertical slit 441. The vertical slit 441 is a narrow slit that extends vertically through the center of the fin member 44. The horizontal slits 442a, 442b, and 442c are narrow slits that extend widthwise of the fin member 44. The horizontal slits 442a, 442b, and 442c are arranged approximately parallel to each other at intervals in the vertical direction of the fin member 44.

As shown in FIG. 8A, the vertical cut 441 extends vertically from the upper end 44a to the lower end 44b of the fin member 44, and crosses the three horizontal cuts 442a, 442b, and 442c. In detail, the vertical cut 441 is composed of an upper vertical cut 441a that extends vertically from the upper end 44a of the fin member 44 to the lowest horizontal cut 442c, and a lower vertical cut 441b that extends from the horizontal cut 442c to the lower end 44b. The upper vertical cut 441a and the lower vertical cut 441b are slightly offset in the width direction of the fin member 44, and are connected at the horizontal cut 442c.

As shown in Figures 7 and 8A, a pair of locking ribs 443a, 443b extending vertically and approximately parallel to the vertical cut 441 are provided on one surface 44c of the fin member 44. The locking ribs 443a, 443b are disposed at both ends of the horizontal cuts 442b, 442c in the extension direction. As shown in Figure 7, the locking rib 443b protrudes higher than the locking rib 443a.

The other surface 44d of the fin member 44 has a plurality of positioning protrusions 444 each protruding therefrom. In the fin member 44 of this embodiment, three positioning protrusions 444 are arranged vertically on each of the outer sides of the locking ribs 443a, 443b. Furthermore, the side end 44e and the lower end 44b on the exterior side of the fin member 44 are formed thick by protruding from the surface 44c in the same direction as the locking ribs 443a, 443b. Of the locking ribs 443a, 443b, the locking rib 443b with the higher protrusion height is arranged on the side end 44e side.

The fin-shaped shielding member 45 is a shielding member that shields the slits of the fin member 44. The fin-shaped shielding member 45 has one vertical slit 451 and two horizontal slits 452a, 452b that are perpendicular to the vertical slit 451. The vertical slit 451 is a narrow slit that extends vertically through the center of the fin-shaped shielding member 45. The horizontal slits 452a, 452b are narrow slits that extend in the width direction of the fin-shaped shielding member 45. The horizontal slits 452a, 452b are arranged approximately parallel to each other at a distance in the vertical direction of the fin-shaped shielding member 45.

As shown in FIG. 8B, the vertical cut 451 extends vertically from the upper end 45a to the lower end 45b of the fin-shaped shielding member 45, and crosses the two horizontal cuts 452a, 452b. In detail, the vertical cut 451 is composed of an upper vertical cut 451a that extends vertically from the upper end 45a of the fin-shaped shielding member 45 to the lowest horizontal cut 452b, and a lower vertical cut 451b that extends from the horizontal cut 452b to the lower end 45b. The upper vertical cut 451a and the lower vertical cut 451b are slightly offset in the width direction of the fin-shaped shielding member 45, and are connected at the horizontal cut 452b.

As shown in Figures 7 and 8B, a pair of locking ribs 453, 453 extending vertically and approximately parallel to the vertical cut portion 451 are provided on one surface 45c of the fin-shaped shielding member 45. The locking ribs 453, 453 are respectively disposed at both ends of the horizontal cut portions 452a, 452b in the extension direction. As shown in Figure 7, the locking rib 453b protrudes higher than the locking rib 453a.

The fin-shaped shielding member 45 is provided with a plurality of positioning recesses 454. The positioning recesses 454 in this embodiment penetrate the fin-shaped shielding member 45. However, the positioning recesses 454 do not have to penetrate the fin-shaped shielding member 45. The positioning recesses 454 are provided in one-to-one correspondence with the positioning protrusions 444 of the fin member 44. Therefore, in the fin-shaped shielding member 45 of this embodiment, three positioning recesses 454 are arranged vertically on both outer sides of the locking ribs 453a and 453b. Furthermore, the side end 45e and the lower end 45b on the exterior side of the fin-shaped shielding member 45 are formed thick by protruding from the surface 45c in the same direction as the protruding direction of the locking ribs 453a and 453b. Of the locking ribs 453a and 453b, the locking rib 453b with the higher protruding height is arranged on the side end 45e side.

The fin member 44 and the fin-shaped shielding member 45 are butted together so that their respective locking ribs 443, 453 are arranged in opposite directions, and are then stacked on top of each other. At this time, the positioning protrusion 444 of the fin member 44 fits into and engages with the positioning recess 454 of the fin-shaped shielding member 45. This positions the fin member 44 and the fin-shaped shielding member 45 relative to each other. Therefore, the positioning protrusion 444 and the positioning recess 454 form the positioning portion of the fin member 44 and the fin-shaped shielding member 45. The surface where the fin member 44 and the fin-shaped shielding member 45 come into contact is flat except for the positioning protrusion 444 and the positioning recess 454. Therefore, the fin member 44 and the fin-shaped shielding member 45 come into close contact by overlapping each other.

The lower end 44b and side end 44e of the fin member 44 and the lower end 45b and side end 45e of the fin-shaped shielding member 45 overlap each other. The locking ribs 443a, 443b of the fin member 44 and the locking ribs 453a, 453b of the fin-shaped shielding member 45 overlap at the same position and protrude in opposite directions.

8A and 8B, when the fin member 44 and the fin-shaped shielding member 45 are stacked on top of each other, the upper vertical cut 441a of the fin member 44 and the upper vertical cut 451a of the fin-shaped shielding member 45 overlap each other. That is, the two upper vertical cuts 441a, 451a are arranged at the same position along the extension direction of the outdoor rail 211. The vertical length of these upper vertical cuts 441a, 451a is approximately equal to the protruding height of the outdoor rail 211 from the upper frame 21. However, the lower vertical cut 441b of the fin member 44 and the lower vertical cut 451b of the fin-shaped shielding member 45 are arranged at different positions shifted in the width direction and do not overlap each other. As a result, the lower vertical cut 441b of the fin member 44 is shielded by the fin-shaped shielding member 45.

Furthermore, when the fin member 44 and the fin-shaped shielding member 45 are overlapped with each other, the horizontal slits 442a, 442b, and 442c of the fin member 44 and the horizontal slits 452a and 452b of the fin-shaped shielding member 45 are arranged at different positions offset vertically and do not overlap with each other. In detail, the horizontal slit 452a of the fin-shaped shielding member 45 is arranged between the horizontal slits 442a and 442b of the fin member 44, and the horizontal slit 452b of the fin-shaped shielding member 45 is arranged between the horizontal slits 442b and 442c of the fin member 44. As a result, the horizontal slits 442a, 442b, and 442c of the fin member 44 are shielded by the fin-shaped shielding member 45.

The fin member 44 and the fin-shaped shielding member 45 are inserted into the fin member housing groove 414 from the side of the anti-vibration member main body 41 so that the thick side ends 44e, 45e are at the rear side of the insertion direction D, with the fin member 44 and the fin-shaped shielding member 45 overlapping each other as shown in FIG. 5. As a result, the fin member 44 and the fin-shaped shielding member 45 are housed in the anti-vibration member main body 41 so as to shield the guide groove 412.

As shown in FIG. 7, the fin member accommodating groove 414 has a start-end opening 414a arranged at the start end side of the insertion direction D of the fin member 44 and the fin-shaped shielding member 45, and a terminal end opening 414b arranged at the terminal end side of the insertion direction D. The width of the start-end opening 414a is greater than the width of the terminal end opening 414b.

In the overlapping fin member 44 and fin-shaped shielding member 45, the thickness dimension of the locking ribs 443a, 453a is approximately the same as the width of the start-end opening 414a, but is larger than the width of the end-end opening 414b. Furthermore, the thickness dimension of each of the locking ribs 443b, 453b and the side ends 44e, 45e is larger than the width of the start-end opening 414a. Therefore, when the fin member 44 and fin-shaped shielding member 45 are inserted into the fin member housing groove 414, the overlapping locking ribs 443a, 453a smoothly pass through the start-end opening 414a and abut against the end-end opening 414b from the inside of the guide groove 412. Just before the insertion of the fin member 44 and the fin-shaped shielding member 45 is completed, the overlapping locking ribs 443b, 453b elastically overcome the starting end opening 414a and are locked into the starting end opening 414a from the inside of the guide groove 412.

Therefore, the fin member 44 and the fin-shaped shielding member 45 inserted into the fin member housing groove 414 are positioned within the fin member housing groove 414 by the locking ribs 443a, 443b, 453a, and 453b. The overlapping side ends 44e and 45e abut against the start end opening 414a when the insertion of the fin member 44 and the fin-shaped shielding member 45 is completed. This prevents the fin member 44 and the fin-shaped shielding member 45 from being inserted excessively into the fin member housing groove 414.

In this way, the anti-sway member 4, with the fin member 44 and the fin-shaped shielding member 45 housed within the anti-sway member body 41, is attached to the upper end portion 34A1 of the outer fitting frame 34A of the outer screen 3A. The outer screen 3A with the anti-sway member 4 attached is erected inside the frame body 2 by housing the exterior rail 211 of the upper frame 21 in the guide groove 412 of the anti-sway member 4 so that it is sandwiched from the indoor/outdoor direction, as shown in Figures 2 and 3.

Next, the effects of the anti-sway member 4 shown in the above embodiment and the sliding window 1 equipped with this anti-sway member 4 will be described. The anti-sway member 4 includes an anti-sway member body 41 having a guide groove 412 that accommodates the outdoor rail 211 so as to sandwich it from the indoor/outdoor direction, a fin member 44 having multiple cuts 441, 442a, 442b, 442c and arranged to close the gap between the outdoor rail 211 and the guide groove 412, and a fin-shaped shielding member 45 that is at least one shielding member that shields the multiple cuts 441b, 442a, 442b, 442c of the fin member 44. As a result, the multiple cuts 441b, 442a, 442b, 442c of the fin member 44 are shielded by the fin-shaped shielding member 45, improving the airtightness of the fin member 44. Therefore, this anti-vibration member 4 can further reduce the inflow of outside air.

The fin-shaped shielding member 45 has multiple horizontal slits 452a, 452b, and the positions of the multiple horizontal slits 442a, 442b, 442c of the fin member 44 are different from the positions of the multiple horizontal slits 452a, 452b of the fin-shaped shielding member 45. This allows the fin member 44 and the fin-shaped shielding member 45 to easily flex and deform in response to the opening and closing movement of the outer screen 3A due to their respective slits. Therefore, with this anti-vibration member 4, the opening and closing movement of the outer screen 3A does not become heavy while improving airtightness and reducing the inflow of outside air.

The fin member 44 and the fin-shaped shielding member 45 overlap each other in close contact. This further improves the airtightness of the anti-vibration member 4.

The fin member 44 and the fin-shaped shielding member 45 each have a positioning protrusion 444 and a positioning recess 454, which are positioning parts that position the fin member 44 and the fin-shaped shielding member 45 by engaging with each other. This prevents the fin member 44 and the fin-shaped shielding member 45 from becoming misaligned within the anti-vibration member body 41 when the outer screen 3A is installed or opened and closed.

The fin member 44 and the fin-shaped shielding member 45 each have vertical slits 441, 451 extending along the height direction of the exterior rail 211, and horizontal slits 442a, 442b, 442c, 452a, 452b extending in a direction intersecting the vertical slits 441, 451. The fin member 44 and the fin-shaped shielding member 45 differ in the positions of at least the horizontal slits 442a, 442b, 442c, 452a, 452b among the vertical slits 441, 451 and the horizontal slits 442a, 442b, 442c, 452a, 452b. As a result, the horizontal cuts 442a, 442b, and 442c of the fin member 44, which are located on the outdoor side and indoor side of the outdoor rail 211, respectively, are shielded by the fin-shaped shielding member 45, further improving the airtightness of the anti-vibration member 4.

The vertical slits 441, 451 of the fin member 44 and the fin-shaped shielding member 45 are each composed of an upper vertical slit 441a, 451a and a lower vertical slit 441b, 451b. The upper vertical slits 441a, 451a of the fin member 44 and the fin-shaped shielding member 45 are arranged in overlapping positions, and the lower vertical slits 441b, 451b of the fin member 44 and the fin-shaped shielding member 45 are arranged in different positions. As a result, when the outer screen 3A is installed, the outdoor rail 211 in the guide groove 412 can be smoothly inserted into the overlapping upper vertical slits 441a, 451a. The opening and closing operation of the outer screen 3A does not become heavy. Furthermore, because the lower vertical slits 441b and 451b do not overlap, the airtightness of the fin member 44 at the lower vertical slits 441b and 451b is also improved.

The anti-vibration member 4 shown in the above embodiment has the fin member 44 and the fin-shaped shielding member 45 stacked on top of each other and removably housed inside the fin member housing groove 414. By housing the fin member 44 and the fin-shaped shielding member 45 inside the fin member housing groove 414, it is possible to construct a highly airtight anti-vibration member 4 and sliding window 1 that can further reduce the inflow of outside air.

Figures 9 and 10 show another embodiment of the shielding member. The fin member 44 is designated by the same reference numeral as in the above embodiment. This shielding member is made of mohair 46.

The mohair 46 is provided in a frame member 461. The frame member 461 is formed in the shape of a thin plate having the same outer shape as the fin member 44, from the same resin as the fin member 44 and soft materials such as rubber. The frame member 461 has the same structure as the fin-shaped shielding member 45 described above, except that the areas corresponding to the vertical slits 441 and the horizontal slits 442a, 442b, and 442c of the fin member 44 are cut out in large rectangular shapes. Therefore, like the fin-shaped shielding member 45, the frame member 461 has a positioning recess 462 that can engage with the positioning protrusion 444 at a position corresponding to the positioning protrusion 444 of the fin member 44.

The mohair 46 is provided so as to cover the rectangular cut-out portion of the frame member 461. The mohair 46 shown in this embodiment is formed in a brush shape and is provided so as to protrude inward from the left and right portions of the frame member 461. However, the mohair 46 is not limited to being brush-shaped, and may be sponge-like, rubber-like, or the like, as long as it has flexibility that allows it to follow the deformation of the fin member 44.

The mohair 46 provided on the frame member 461 is positioned relative to the fin member 44 and closely overlapped in place of the fin-shaped shielding member 45 described above. The fin member 44 and the mohair 46 are inserted in the overlapped state into the fin member accommodation groove 414 of the anti-vibration member main body 41 in the same manner as described above. As a result, as shown in FIG. 10, the vertical slit 441 and the horizontal slits 442a, 442b, and 442c of the fin member 44 accommodated in the anti-vibration member main body 41 are substantially shielded by the mohair 46. Therefore, the effect of improving the airtightness of the fin member 44 is obtained, similar to the case where the fin member 44 and the fin-shaped shielding member 45 are overlapped with each other.

In FIG. 9, the mohair 46 is positioned further back (inside) of the anti-vibration member body 41 than the fin member 44, but it may also be positioned closer to the front (outside) of the anti-vibration member body 41 than the fin member 44. The mohair 46 as a shielding member may be provided directly on the anti-vibration member body 41 so as to block the guide groove 412 of the anti-vibration member body 41. In order to further improve the airtightness of the fin member 44, the anti-vibration member 4 may use the fin-shaped shielding member 45 and mohair 46 described above as shielding members.

Next, the mounting body will be described using Figures 11 to 15. In Figure 11, parts with the same reference numerals as the anti-vibration member 4 in the above embodiment indicate parts with the same configuration. Therefore, detailed descriptions of those parts will be omitted below, as the descriptions in the above embodiment will be used.

Figure 11 shows an anti-vibration member 4A in which an attachment 5 is attached to the front plate portion 411 of the anti-vibration member main body 41. The attachment 5 in this embodiment is composed of a storage case 51, a fin member 53 which is an airtight member stored in the storage case 51, and a fin-shaped shielding member 54 which is a shielding member that is layered on the fin member 53 and supplementarily enhances the airtightness of the fin member 53.

The storage case 51 is made of a rectangular resin or metal plate such as aluminum that is slightly larger than the front plate 411 of the anti-vibration member main body 41. The storage case 51 is provided with a notched groove 511 cut into a vertically elongated rectangular shape from the upper end 51a to the lower end 51b, and a screw insertion hole 512. The notched groove 511 is disposed at a position corresponding to the guide groove 412 of the anti-vibration member main body 41. The width and depth of the notched groove 511 are approximately the same as the width and depth of the guide groove 412. The screw insertion hole 512 has approximately the same size as the screw insertion hole 411a of the front plate 411, and is disposed at a position corresponding to the screw insertion hole 411a.

As shown in FIG. 13, a fin member attachment groove 513 is provided on the back surface 51c of the storage case 51. The vertical and width dimensions of the fin member attachment groove 513 are slightly larger than the vertical and width dimensions of the notch groove 511. The fin member attachment groove 513 is composed of vertical deep groove portions 513a, 513a arranged on both outer sides of the notch groove 511, and a horizontal deep groove portion 513b arranged below the notch groove 511. The horizontal deep groove portion 513b connects the lower ends of the vertical deep groove portions 513a, 513a.

A pair of wall panels 514, 514 extend vertically along both sides of the storage case 51 on the rear surface 51c of the storage case 51. The distance between the inner surfaces of the pair of wall panels 514, 514 is approximately the same as the width of the front panel 411. The lower ends of the wall panels 514, 514 extend to the lower end 51b of the storage case 51. However, the upper ends of the wall panels 514, 514 are positioned below the upper end 51a of the storage case 51.

As shown in FIG. 12, the fin member 53 and the fin-shaped shielding member 54 are attached to the fin member attachment groove 513 from the rear surface 51c side of the storage case 51. The fin member 53 and the fin-shaped shielding member 54 are flexible, being formed into a rectangular thin plate shape from soft materials such as resin and rubber, similar to the fin member 44 and the fin-shaped shielding member 45 described above. The fin-shaped shielding member 54 is slightly larger than the fin member 53.

As shown in FIG. 14, the fin member 53 has one vertical slit 531 and three horizontal slits 532a, 532b, and 532c that are approximately perpendicular to the vertical slit 531. The vertical slit 531 is a narrow slit that extends vertically through the center of the fin member 53. The horizontal slits 532a, 532b, and 532c are narrow slits that extend in the width direction of the fin member 53. The horizontal slits 532a, 532b, and 532c are arranged approximately parallel to each other at intervals in the vertical direction of the fin member 53.

The fin-shaped shielding member 54 has one vertical slit 541 and three horizontal slits 542a, 542b, and 542c that are approximately perpendicular to the vertical slit 541. The vertical slit 541 is a narrow slit that extends vertically through the center of the fin-shaped shielding member 54. The horizontal slits 542a, 542b, and 542c are narrow slits that extend widthwise of the fin-shaped shielding member 54. The horizontal slits 542a, 542b, and 542c are arranged approximately parallel to each other at intervals in the vertical direction of the fin-shaped shielding member 54.

When the fin member 53 and the fin-shaped shielding member 54 overlap, the vertical slits 531 and 541 are arranged so as to overlap at the same position. However, the horizontal slits 532a, 532b, and 532c of the fin member 53 and the horizontal slits 542a, 542b, and 542c of the fin-shaped shielding member 54 are arranged at different positions and do not overlap. As a result, the horizontal slits 532a, 532b, and 532c of the fin member 53 are shielded by the fin-shaped shielding member 54.

As shown in Figures 12 and 14, a positioning rib 533 extends along both side edges and the bottom edge of the fin member 53 on the surface 53a of the fin member 53. A positioning rib 543 extends along both side edges and the bottom edge of the fin-shaped shielding member 54 on the surface 54a of the fin-shaped shielding member 54. The fin member 53 is overlapped so as to fit inside the positioning rib 543 of the fin-shaped shielding member 54. This positions the fin member 53 and the fin-shaped shielding member 54 in close contact with each other. The positioning rib 533 of the fin member 53 and the positioning rib 543 of the fin-shaped shielding member 54 form positioning portions for the fin member 53 and the fin-shaped shielding member 54.

The fin member 53 and the fin-shaped shielding member 54 are stacked and attached to the fin member attachment groove 513 from the back surface 51c side of the storage case 51 as shown in FIG. 12. The fin member 53 and the fin-shaped shielding member 54 are fitted into the vertical deep groove portion 513a and the horizontal deep groove portion 513b of the fin member attachment groove 513 with the positioning rib 533 of the fin member 53 placed inside the positioning rib 543 of the fin-shaped shielding member 54. The fin member 53 and the fin-shaped shielding member 54 fitted into the fin member attachment groove 513 are positioned so as to block the notched groove 511 of the storage case 51 as shown in FIG. 11 and FIG. 12.

As shown in FIG. 11, the attachment 5 with the fin member 53 and fin-shaped shielding member 54 attached in this manner is attached to the front plate 411 of the anti-vibration member main body 41 with double-sided adhesive tape or the like, with the back surface 51c of the storage case 51 facing the anti-vibration member main body 41. The wall plate portions 514, 514 on both sides of the storage case 51 are positioned to sandwich the front plate portion 411 in the width direction. This positions the attachment 5 relative to the anti-vibration member main body 41.

With this attachment 5, the horizontal notches 532a, 532b, and 532c of the fin member 53 are shielded by the fin-shaped shielding member 54, so that a highly airtight anti-vibration member 4A capable of reducing the inflow of outside air can be easily constructed simply by retrofitting it to the front plate portion 411 of the existing anti-vibration member main body 41.

Even in this attachment 5, the fin-shaped shielding member 54, which is a shielding member, overlaps closely with the fin member 53. This further improves the airtightness of the fin member 53.

The overlapping fin member 53 and fin-shaped shielding member 54 are positioned and overlapped by a positioning section consisting of positioning ribs 533 and 543. This prevents the fin member 53 and fin-shaped shielding member 54 from shifting position within the mounting body 5 when the outer screen 3A is installed or opened and closed.

The anti-vibration member main body 41 to which the attachment 5 is later attached is not limited to one that houses the fin member 53 and the fin-shaped shielding member 54 as described above. In the anti-vibration member 4A provided with the attachment 5 that includes the fin member 53 and the fin-shaped shielding member 54, the horizontal cuts 532a, 532b, and 532c of the fin member 53 arranged on the attachment 5 are shielded by the fin-shaped shielding member 54, which is a shielding member, so the anti-vibration member main body 41 does not need to be provided with the fin-shaped shielding member 54, and neither does it need to be provided with the fin member 44.

When the anti-vibration member main body 41 has only the fin member 44, the mounting body 5 may be provided with only the fin-shaped shielding member 54, which is a shielding member. When the mounting body 5 is retrofitted to the anti-vibration member main body 41, the multiple slits of the fin member 44 of the anti-vibration member main body 41 are substantially shielded by the fin-shaped shielding member 54 of the mounting body 5. In this case, the fin member 44 of the anti-vibration member main body 41 and the fin-shaped shielding member 54 of the mounting body 5 are in close contact and do not overlap, but the slits of the fin member 44 and the fin-shaped shielding member 54 are positioned at different positions to form a labyrinth structure, which makes it possible to reduce the inflow of outside air.

The attachment that is attached to the anti-vibration member may have mohair as a shielding member. Figure 15 shows an anti-vibration member 4B to which an attachment 5A having mohair 55 is attached. The parts with the same reference numerals as those in Figure 11 have the same configuration, so the detailed description of those parts is omitted below, and the above description is used as a reference.

In the attachment 5A, the mohair 55 is provided so as to protrude from both the left and right edges 511a, 511b of the cutout groove 511 of the storage case 51 in opposing directions. When this attachment 5A is retrofitted to the anti-vibration member main body 41, the guide groove 412 of the anti-vibration member main body 41 is blocked by the mohair 55, and the multiple notches of the fin member 44 provided on the anti-vibration member main body 41 are essentially shielded by the mohair 55. This further improves the airtightness of the anti-vibration member main body 41. This mohair 55 is also formed in a brush shape, but may be in a sponge shape, rubber shape, etc.

In FIG. 15, the anti-vibration member main body 41 contains a fin member 44 and a fin-shaped shielding member 45, but if the attachment body 5A is provided with mohair 55, the anti-vibration member main body 41 may be provided with only the fin member 44.

The attachment body 5A may be provided with a fin member as an airtight member in addition to the mohair 55. In this case, the mohair 55 is closely stacked on the fin member of the attachment body 5A and can shield the multiple notches of the fin member, so the anti-vibration member main body 41 does not necessarily need to be provided with a fin member.

Two or more fin-shaped shielding members 45, 54, which are shielding members, may be provided for each fin member 44, 53, which is an airtight member.

The anti-sway members 4, 4A described above are provided on the upper end 33A1 of the outer meeting frame 34A of the outer screen 3A. However, the anti-sway members 4, 4A may be provided on the lower end of the outer meeting frame 34A, or on at least one of the upper and lower ends of the inner meeting frame 34B of the inner screen 3B. The windows to which the anti-sway members 4, 4A are attached are not limited to sliding windows. The anti-sway members 4, 4A may be attached to the movable screen of a single sliding window, for example.
